smart mdi study (cip343)

Conditions: Diabetes Mellitus, Type 1

Summary: the purpose of the study is to evaluate the effectiveness of the smart mdi system with inpen™ and simplera™ in comparison with multiple daily injection (mdi) therapy with intermittent scanning or real-time continuous glucose monitoring (iscgm/cgm) over 6 months duration in people with type 1 diabetes to support the market access and therapy adoption of the smart mdi system.

this is a post-market, prospective, open-label, multi-center, randomized controlled trial in adult and pediatric subjects with type 1 diabetes. the study consists of a run-in phase of 3 weeks and a study phase of 6 months. the purpose of the run-in phase is to collect baseline hba1c and cgm data while subjects are on their current therapy. during the 6-month study phase, subjects will be randomized to continue with their current therapy or to start using the smart mdi system. approximately 140 subjects with type 1 diabetes aged 2 years and older will be enrolled in the study at up to 20 investigational centers in europe to achieve approximately 112 subjects randomized and completing the 6-month study phase.

Eligibility criteria:
inclusion criteria: 1. subject is age 2 years or older at time of screening. 2. subject is on mdi therapy (defined as ≥ 3 insulin injections per day and on a basal/bolus regimen) ≥ 6 months prior to screening. 3. subject has a clinical diagnosis of type 1 diabetes for ≥ 12 months. 4. subject is on mdi therapy with intermittent scanning or continuous glucose monitoring (iscgm/cgm) ≥ 3 months prior to screening. 5. subject has high compliance with sensor wear, per investigator assessment. 6. subject has a glycosylated hemoglobin (hba1c) ≥ 8% (64 mmol/mol) as assessed locally at time of screening visit. 7. subject is willing to take or switch to one of the inpen-compatible insulin types, novorapid™, fiasp™, humalog™ and lyumjev™. 8. subject or parent(s)/legal guardian(s) has a compatible mobile phone with internet access. 9. subject or parent(s)/legal guardian(s) is willing and able to provide written informed consent, comply with all study procedures and wear all study devices, as required during the study. exclusion criteria: 1. subject is using a medtronic inpen™ for at least 3 months prior to screening. 2. subject has untreated/unstable addison's disease, growth hormone deficiency, hypopituitarism or definite gastroparesis, untreated coeliac disease, untreated thyroid disorder, or poorly controlled asthma, per investigator judgment. 3. subject is planning to initiate or change to another glucose modifying therapy (for example pramlintide, dpp-4 inhibitor, glp-1 agonists/mimetics, metformin or sglt2 inhibitors). 4. subject has taken any oral, injectable, or intravenous (iv) glucocorticoids within 8 weeks from time of screening visit, or plans to take any oral, injectable, or iv glucocorticoids during the course of the study chronically. 5. subject has renal failure (stage 4 and above) defined by creatinine clearance of \&lt;30 ml/min, as assessed by local lab test ≤ 6 months before screening or performed at screening at local lab, as defined by the creatinine-based cockcroft, ckd-epi or mdrd equations. 6. subject has any unresolved adverse skin conditions in the area of sensor placement (e.g. psoriasis, dermatitis herpetiformis, rash, staphylococcus infection). 7. subject is actively participating in an investigational study (drug or device) wherein he/she has received treatment from an investigational study drug or device in the last 2 weeks before enrollment into this study, as per investigator judgment. 8. subject is currently abusing illicit drugs, marijuana, alcohol or prescription drugs (other than nicotine), per investigator judgment. 9. subject has any other disease or condition that may preclude the patient from participating in the study, per investigator judgment. 10. subject is a woman of child-bearing potential who has a positive pregnancy test at screening or plans to become pregnant during the course of the study. 11. subject is a woman who is breastfeeding. 12. subject or parent(s)/legal guardian(s) is legally incompetent, illiterate or a vulnerable person. 13. subject is a member of the research staff involved with executing the study.
